// Package exec provides utilities for executing system commands with Either-based error handling.
package exec

)

var (
	// Command executes a system command and returns the result as an Either.
	// Use this version if the command does not produce any side effects,
	// i.e., if the output is uniquely determined by the input.
	// For commands with side effects, typically you'd use the IOEither version instead.
	//
	// Parameters (curried):
	//   - name: The command name/path
	//   - args: Command arguments
	//   - in: Input bytes to send to the command's stdin
	//
	// Returns Result[CommandOutput] containing the command's output or an error.
	//
	// Example:
	//
	//	result := exec.Command("echo")( []string{"hello"})([]byte{})
	//	// result is Right(CommandOutput{Stdout: "hello\n", ...})
	Command = exec.Command
